SETTING FOB PRECIOUS STON-EE.

Specification of Letters Patent.

Patented Aug. 2c, 1918.

Application filed February 27, 1917. Serial No. 151,153.

To all 'UJ/I/OJIL it may concern:

l lo it known that l, ABRAHAM Suonsov, a citizen of the United States ofAmerica, residing at New York, N. 'Y., have invented a new and usefulSetting for Precious Stones, of which the following is a specification.

My present invention is a setting for out stones and aims primarily toprovide a setting in which number of small stones can be made toresemble a single large cut stone.

Other objects are to provide a setting which can be readily made up andmounted, in which the small stones can be easily placed and which willbe neat and attractive in appearance.

Briefly, the invention involves the provision of a frame having anarched top and a substantially conical back, in substantial resemblanceto the shape of a cut stone, said frame having openings in the topthereof in positions substantially corresponding to the planes of a cutstone of the size of the frame and relatively small cut stones seated insaid openings with their faces in substantially the planes of a cutstone the size of the frame. The back of the frame is left open usuallyby the provision of longitudinal slots, in the planes of the rear facetsof a cut stone the size of the frame, the effect being on the whole thatof a single cut ston the size of the frame.

In the accompanying drawing 1 have shown my invention embodied in apractical and preferred form, but changes and modifications may beindulged in without departing from the true spirit and scope of theinvention.

Figure 1 is a side view of the invention as applied to a finger ring.

Fig. 2 is an enlarged top plan view of the same.

Fig. 8 is a sectional view of the setting taken substantially on theplane of the line 3--3 of Fig. 2.

Figs. 5 and 5 are sectional views of the top and back portions of theframe before being united.

Figs. 6 and 7 are plan views of the back and the top respectively beforethey have been shaped.

The frame which comprises the body or base of the setting is shaped tocorrespond generally to the configuration of a cut stone, that is, witha substantially arched top 10 and a substantially conical or pyramidalback ll. In the particular construction herewith disclosrd the topandthe back are made as two separate parts which are stamped to shape, andthen secured together at their edges as shown in Fig. 3. The top is madefrom a flat disk 12 which is arched up into the form shown in Fig. 41-,and the back is made from a. star-shaped blank 13 like that shown inFig. 6 which is depressed at the center to give it the substantiallypyramidal shape shown in Fig. 5. The two parts are then united bybringing the points of the star shaped member into engagement with therim of the top and securing them by means of solder or the likeindicated in Fig. 3. The frame thus produced is in the nature of a cagehaving the general configuration of a cut diamond or other preciousstone.

The top is provided with openings 14 forming seats for the relativelysmall cut stones 15. The seats are so disposed that when the stones arein place they will occupy positions corresponding to the table andfacets of a cut stone of the size of the setting frame-in other wordsthe face of each cut stone represents one face of a cut stone the sizeof the frame. These stones may be secured in. place by suitable meanssuch as striking up tangs 16 engaging over the edge of the stones.

The frame is left open at the back so as to expose the backs of therelatively small cut stones. In the illustration openings 17 are leftbetween the arms of the star shaped blanks and in addition these armsare shown longitudinally slotted as indicated at 18. These slots arelocated in the planes of the seats in the top of the setting as shown inFig 2, so that from the side the backs of the stones may be seen throughthese slots, this serving to produce the effect given by the back of acut stone. This effect is further heightened by punching a relativelysmall opening 19 in the center of the back, this serving to give theeffect of the so called hole in the back of a cut diamond.

The cluster construction as above described constitutes a single unitwhich while made of relatively small stones resembles a single large cutstone, the frame being usually made of platinum or other white metal.which when polished, shows off the stones without itself being tooprominent.

In mounting the cluster in a ring for instance, the cluster ispreferably so set that the effect of the rear facets on the back of acut stone.

I claim:

A jewel setting comprising a top member having a plurality of passagestherethrough forming jewel seats, a plurality of downwardly extendingconvergent arms symder'the center of said top member the space betweensaid arms and said top member being unobstructed, said arms each being1011- gitudinally slotted, the slot extending almost but not quite fromone end to the'other, those partsof thearms on opposite sides of theslots being bowed outwardly away from each other to form a plurality ofcurved light reflecting surfaces.
